A message from the Founder

"I started Control Freq in March 2007 with an idea of mobile-based access control. In hindsight, it was a bit early as mobile hadn't taken hold as it has today. ControlFreq has since expanded into many industries, globally, with a wide range of applications. Now, 14 years on, in 2021, times have changed, and so have we. ControlFreq2.0 is launching Q4 2021 with a dedicated focus on providing trade installers & technology integrators the latest mobile hardware, custom software & associated services to achieve more for their clients, with our support".

The ControlFreq Back Story

Control Freq was started by Noel Sesto in 2007. Noel was born in London and moved to Australia with his family when he was 6 years old. He began working for a company called Bollinger Automatic from the age of 19, training as an Electrical Engineer. After many years experience in automation, access control, door entry, alarm, CCTV and integrated solutions, he made a move to Europe to spend a few years in Spain with family. After a couple of years travelling the world, he finally decided to set up a business in London based around his own professional experience in the access, door entry and automation industry. Control Freq was born.

The idea to set up a business came about from an understanding within the automation industry, in particular Property Management. Working with Property Managers he recognised constant user access issues. So many properties, so many gates and doors, PIN codes, keyfobs, all different brands, tenants moving in and out, lost fobs or broken fobs. This was and still is a major hassle on a daily basis for a Property Manager. Then there's stolen fobs that can't be removed from the system individually which compromise property security. So with all that in mind, Noel decided to come up with an idea that made all of that go away. One universal solution that meant every property could be accessed by multiple people and managed remotely without any hassle. This is what he developed...

Solving a problem is great, or so he thought. The bigger problem was, Property Managers didn't seem to see it the same way. See in 2007, mobile phone technology was not as it is today. It was not an intrinsic part of our daily lives, as it is now. They told him "no way, controlling gates with mobile phones will never take off"... 

Here's a testimonial from a Property Manager he helped in the years to follow. As it happens, Property Managers are now a substantial part of Control Freq's customers.

In any case, not to be put off, Noel set off with a new vision, to find a new problem using the same GSM mobile technology to solve it. He looked inwards, into his own experience, his own frustrations, his own view of what was and wasn't available and how they could be better. This is when the GSM intercom was born.

The GSM intercom became the foreseeable future for Control Freq. That said, Control Freq has always provided solutions and never serviced just one market. GSM intercoms for Control Freq opened up many other opportunities aside from the typical door entry / security market. It is now used as a Taxi freephone, emergency phone, hotel / B&B after hours intercom, information call point, home door entry, business door entry, apartment door entry to name a few. 

Control Freq has gone on to develop 3G / GSM alarm monitoring for properties, plant & equipment, remote control applications and even remotely manageable access control for car parking providers. 



The changing face of the world, as with any disaster, has brought about many new opportunities. ControlFreq used the 1st lockdown to re-evaluate what we do, why we do it and who we do it for. This was a momentus breakthrough and realignment of what we were to do when we returned. 

ControlFreq is very much focused on the after sales services our products support rather than just the products themselves. The hardware forms only part of the overall solution so we decided to develop a customer relationship methodology that provides what the customer needs end-to-end including not just hardware but also SIM card connectivity, web-based monitoring, tailored 'value-add' services and ongoing support.

The two core areas of expertise in ControlFreq are access control and alarm monitoring. Our access control is employed in on-demand parking sites all over the U.K. operated by our customers, the parking apps. Parking slowed down during the pandemic however there was another industry starting to peak, alarm monitoring.

At the end of 2020, ControlFreq signed a 700 site UK/EU rollout deal with a major high st retailer with global reach. The combination of hardware, connectivity, web-based software and ongoing support has allowed them to streamline their alarm system monitoring in-house which reducing their operating costs compared to the previous monitoring system being replaced.

ControlFreq is now applying this same methodology to new customers looking for a product & service provider all-in-one.


"If you appreciate exceptional service, after sales support and expert advice, don't listen to us, see what our customers have to say".
